ValidTo vs Wiza: Email Verifier or Email Finder?
Your last cold email campaign bounced 19% of the list. The data vendor swore those emails were verified. Now your domain reputation's taken a hit, and you're staring at two tools that seem like they solve the problem - but they don't solve the same problem.
Comparing ValidTo vs Wiza is really about sequencing your budget between two different jobs. ValidTo cleans the emails you already have. Wiza finds new ones you don't. Email finding is offense: creating net-new pipeline opportunities. Email verification is defense: protecting deliverability and domain reputation. This isn't a feature war - it's a workflow decision.
30-Second Verdict
- Pick ValidTo if you already have email lists and need to scrub them before sending. It's a dedicated verifier at roughly $0.001 per check.
- Pick Wiza if you need to build prospect lists from scratch and want emails discovered and verified in one workflow.
What Each Tool Actually Does
ValidTo
ValidTo is a pure email verification service. You upload a list or hit their API, and it runs SMTP verification, MX record checks, catch-all detection, anti-greylisting checks, temporary/disposable email detection, spamtrap indicators, syntax checks, and duplicate removal to tell you which emails are safe to send. That's the entire product - no prospecting, no contact discovery, no enrichment.
You get 100 free credits on signup, no credit card required.
Think of it as list hygiene infrastructure. It won't help you find anyone new, but it keeps your sender reputation intact when you're working with purchased lists, event data, or aging CRM records. (If you're troubleshooting bounces end-to-end, see our email deliverability guide and email bounce rate benchmarks.)
Wiza
Wiza is a prospecting platform built around a Chrome extension. It discovers contact information from professional profiles, verifies emails in real time, and enriches each record with 40+ fields - headcount, revenue, funding where available. Wiza claims you can discover 850M+ prospects through its workflow, though that coverage depends on profile completeness rather than a standalone proprietary database. (For more list-building approaches, see sales prospecting techniques and our guide to Clay list building.)
Wiza's built-in verification runs syntax, domain, SMTP, MX, catch-all, disposable email, role-based, spam trap, graylist-proof, and risk validation checks. Emails get classified as "valid" (97% deliverability) or "risky" (50-70% deliverability). Here's a detail worth knowing: risky exports don't consume credits. We've seen smart teams route risky emails to a separate sending domain and sequence rather than mixing them into primary campaigns. (Related: email velocity and how to improve sender reputation.)
With a 4.5/5 rating on G2 across roughly 1,142 reviews, Wiza has strong user satisfaction. It integrates with Salesforce, HubSpot, Outreach, and Pipedrive, and includes job change monitoring via Wiza Monitor. The core value: turn a search into a clean, enriched prospect list without leaving your browser.

They're comparable only if you're deciding where to spend budget first: list hygiene or list building. Wiza's verification is baked into the finding and export workflow - it's not designed as a bulk list-hygiene product the way ValidTo is. ValidTo has zero prospecting capability. If you need both, you're either stitching two tools together or looking for a single platform that handles the full pipeline. (If you're evaluating broader stacks, compare options in our best sales prospecting databases roundup.)
You shouldn't need two tools to find emails and verify them. Prospeo combines email discovery across 300M+ profiles with proprietary 5-step verification - delivering 98% accuracy at ~$0.01 per email. No stitching ValidTo and Wiza together. No export caps.
Find, verify, and enrich contacts in one workflow for a penny each.

|---|---|---|---|
| Pay-as-you-go | Varies | Example: $40 for 30,000 | ~$0.0013 |
ValidTo's pricing is dead simple. API usage is included in the same plan, and pay-as-you-go credits never expire - a nice touch if your verification needs are lumpy. At scale, you're paying fractions of a penny per check.
Wiza Pricing
| Plan | Price | Emails included | Cost/email |
|---|---|---|---|
| Free | $0/user/mo | 20/mo | $0 |
| Starter | $49/user/mo | 100/mo | $0.49 |
| $99/user/mo | 500/mo | $0.20 | |
| Email + Phone | $199/user/mo | 500 emails + 500 phones | $0.20/email |
| Email (annual) | $83/user/mo | "Unlimited" (30K/yr exports) | ~$0.033 |
| Email + Phone (annual) | $166/user/mo | "Unlimited" (30K/yr exports) | ~$0.066 |
Overages hit at $0.15 per extra email and $0.35 per extra phone number.
Watch the fine print: Wiza's annual "Unlimited" plans cap exports at 30,000 per year - roughly 2,500 per month. If you're running high-volume outbound, you'll hit that ceiling faster than you'd expect.
The per-email cost on Starter ($0.49) is steep compared to dedicated verifiers, but you're paying for discovery, not just validation.
Key Drawbacks
Where ValidTo Falls Short
ValidTo has no email finding capability whatsoever. If you don't already have a list, it can't help you. Its third-party review presence is thin - if your team requires heavy G2 or Capterra review volume for vendor approval, ValidTo will slow that process down. The product does one thing well, but the lack of brand visibility outside its own site is a real consideration for enterprise procurement teams running formal evaluations.
Where Wiza Falls Short
The "unlimited" export caps are the biggest frustration. Teams sign up for annual plans expecting uncapped usage and discover the 2,500/month ceiling buried in the details. That's genuinely annoying.
Beyond that, the recurring complaints across Reddit threads and G2 reviews cluster around three themes:
Billing and cancellation friction--including a no-refund policy and credit counter inconsistencies that leave users feeling nickel-and-dimed. Accuracy outside North America drops noticeably for EMEA and LATAM contacts, which matters if you're running global campaigns. Data formatting is the third pain point: exports sometimes come through in all caps with messy company names, creating cleanup work before you can feed data into sequences. (If you're standardizing records, see our overview of data enrichment services.)
What users consistently praise is the extension UX, speed of list building, and real-time verification that filters out obvious bounces before export. Wiza's verification is solid for a prospecting tool - it just isn't a replacement for a dedicated verifier on high-stakes sends.
Choose Based on Your Workflow
Let's stop comparing features in a vacuum. Here's the decision framework:
Cleaning purchased lists or CRM exports? ValidTo. You already have the data; you just need to know what's safe to send.
Building lists from professional profiles? Wiza. You need contacts you don't have yet, enriched and ready for sequences.
Phone-first outbound matters? Prospeo again. 125M+ verified mobiles with a 30% pickup rate is a different league from email-only tools.
Here's the thing: if your deal size is under $15K and your total addressable list is under 50,000 contacts, you don't need both a finder and a verifier as separate line items. Pick one platform that does both and spend the savings on better copy. (If you want help tightening messaging, use these email subject line examples.)
Why Teams Pick a Combined Platform Instead
Why choose between a finder and a verifier? Prospeo combines both: 300M+ professional profiles, 143M+ verified emails, 98% accuracy, and a 7-day data refresh cycle. You get email finding, real-time verification, and 50+ data points per contact in a single workflow - at roughly $0.01 per email with 75 free emails per month. Self-serve, no contracts.
For teams weighing ValidTo vs Wiza, that eliminates the tradeoff entirely. Prospeo's proprietary 5-step verification process includes catch-all handling, spam-trap removal, and honeypot filtering - matching or exceeding what dedicated verifiers offer, while also giving you a full prospecting database with 30+ search filters including buyer intent and technographics. We've tested the accuracy head-to-head, and the bounce rates speak for themselves: customers like Stack Optimize report deliverability above 94% with bounce rates under 3%.
Wiza caps annual exports at 30K. ValidTo can't find a single email. Prospeo gives you 143M+ verified emails, 125M+ mobile numbers, and 30+ search filters - with data refreshed every 7 days, not 6 weeks. No annual contracts, no hidden ceilings.
Get enterprise-grade prospecting and verification without the enterprise pricing.
FAQ
Is ValidTo more accurate than Wiza for verification?
ValidTo is a dedicated verifier, so it edges out Wiza's built-in checks for pure list cleaning. Wiza claims 97% deliverability on "valid" emails and 50-70% on "risky" ones. For high-stakes sends where bounce rates directly impact domain reputation, a dedicated verifier gives you an extra layer of confidence - though Prospeo's 5-step verification process hits 98% accuracy while also handling the finding side.
Can you use ValidTo and Wiza together?
Yes - use Wiza to discover emails, then run them through ValidTo for a second verification pass. This filters out risky or undeliverable addresses but means paying for two tools and managing two workflows. Prospeo eliminates this by combining finding and verification in one platform.
Does Wiza have a free plan?
Wiza's free tier includes 20 emails and 5 phone numbers per month. ValidTo offers 100 free verification credits on signup. Prospeo gives you 75 free emails plus 100 Chrome extension credits monthly - the most generous free tier of the three for teams running real outbound.
